After they left the tree, Silva got permission from the emperor, permission to fly in their airspace. So he transformed into his dragon form and took them on his back.
Silva's dragon had grown quite a bit over time, even though he hadn't noticed it yet, but his size was bigger and his scales lustrous.
He shot through the air like a bullet, but within the speed that the people on his back were safe.
The whole empire underneath him were shocked to see a dragon flying freely, but all army bases had been told not to move against him.
It took a few hours of flying and Silva arrived at the city that they needed to be, and with air clearance, he could land without a single issue.
After landing, he transformed back to normal, and then the main task started.
